I just bought a set for my 2001 because the swingarm has no spool tabs. I didn't know that there is another bracket required for installing the adjusters unless you want to drill and tap your swingarm. (I'm not talking about the lifter brackets.) I would have preferred to have the brackets, but decided to drill and tap. You also have to drill and make countersink holes in the brand new chain adjusters to use this method. All the hardware is included in the kit for either method. Word of advice, drill the swingarm with the adjusters mounted instead of marking and removing. I can guarantee placement of the holes and trueness of the tap will be better. Nice quality pieces and super light. Accuracy of chain adjustment is vastly improved and the axle stays put when torquing now. Good system even for someone who isn't looking for just a way to lift the rear end.
